I found a bug when exporting object with animation.
Animation object is not correctly exported, is not exported at all or with errors.
Thanks for providing a sample model. I had a quick look and noticed that all the doors with incorrect animations have negative scaling applied. I reset the transform on all the doors and the animations export properly now.
In general, I recommend not applying negative scales to objects, because it can cause all kinds of strange issues like this. I'll still try to fix the exporter to support negative scales on animations though.
